Veterinary bacteriology: information about important bacteria
|Category:||In the normal flora|
|Etymology:||Genus name: bunch of grape-like cocci (coccus means a grain or berry).|
Species epithet: from a human. Named after Arthur Warner, from whom this bacterium was first isolated.
|Significance:||[Of minor importance]|
|Type Strain:||ATCC 27836 = CCUG 7325 = NCTC 11044.|
|Macromorphology (smell):||Form medium sized colonies (3-5 mm in diameter), which are circular, glistening and opaque. The colonies are usually sticky and some strains produce a yellowish pigment.|
|Micromorphology:||Non-motile cocci (spherical) with a diameter of 0.5-1.2 µm, whith appear singly, in pairs and in tetrads.|
|Gram +/Gram -:||G+|
|Other Enzymes:||Koagulase -|
|Fermentation of carbohydrates:||
Does not ferment fucose and cellobiose. cf. Staphylococcus sciuri subsp. sciuri).
|Disease:||May cause skin infections in individuals with a compromised immune system. It has been suggested that this bacterium can cause spontaneous abortion in cattle and humans.
|Hosts:||Belongs to the normal skin flora in animals and humans.|
|16S rRNA Seq.:|
|Taxonomy/phylogeny:||About 70 species and subspecies have been described within the genus Staphylococcus.|
|New names of bacterial phyla|
The taxonomic category phylum was previously not regulated by the International Code of Nomenclature of Prokaryotes (ICNP), but now this has changed and it was decided to revise the names of bacterial phyla. All phyla must be written in italics (which has been done on VetBact also before) and have the ending -ota.Published 2023-03-01. Read more...
|The taxonomy of chlamydias|
Species within the family Chlamydiaceae were previously divided into two genera Chlamydia and Chlamydophila. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned to the genus Chlamydia and this change has now been incorporated in VetBactPublished 2023-03-15. Read more...
